The Home button got smarter with firmware 2.2

Although only about 0.79 (74 / 10,000 * 100 = 0.79) per cent of all App Store applications are installed on my iPhone, it got crowded: five pages filled with 74 icons.
If you need to get from your last installed application to the very first, that means a lot of swiping. But Apple made the Home button even more intelligent with 2.2. When you are on one of your Home screens (where your application icons are) a press of the Home button will propel you right to the first Home screen. Maybe this will convince you to finally upgrade.
